The Japanese company called Taxan is going to release these Bluetooth headphones (based on Yamaha gear) with a control system that is worn around the neck. They’re 37×77.5x14mm and weigh 48g. The technology used is Bluetooth 1.1 and they’re MPEG-4 HE AAC compatible. These headphones can be used with AU’s W41T phone (you know, that model with 4GB of memory).
